Feature request: tooltip on individual points on a box plot

[mujahidfa]

This is a very handy library, thank you @sgratzl!

Feature request: It would be great if we can allow for tooltips in all individual points in the box plot and not only for the outlier.

User story

I would like to add further information on the individual points that are displayed via tooltip when user hovers over the specific points. So when user hovers over a point, it will know further custom context about how the point was introduced in the boxplot, and that information ideally will be displayed via a tooltip, triggered on point hover.

However, as of now, it is only possible to trigger a tooltip on hover on the outlier point only (based on #30).

Considering that it is already possible to trigger a tooltip on the outlier point, what would it take (implementation-wise on the library, not user-side) for you to enable tooltips on all individual points and not just on the outlier point? Is this something that you think is possible to further implement in this library? This would be very handy and make this library a lot more useful that can cover more use cases for boxplot visualization.

Thank you!
